Check List

At regular intervals of approximately 5000 miles or when a solo motorcycle develops handling irregularities at high speed, check the following list for possible causes:

1. Loose wheel axle nuts. Tighten to 50 ft-lbs maximum.

2. Excessive wheel hub bearing play.

3. Loosened spokes.

4. Rear wheel out of alignment with frame and front wheel.

5. Rims and tires out-of-true sideways (tire run-out should not be more than 3/64 in.).

6. Rims and tires out-of-round or eccentric with hub (tire run-out should not be more than 3/32 in.).

7. Irregular or peaked front tire tread wear. Replace tire if handling is affected.

8. Tires over-inflated. Check "Tire Data" Section. Do not over-inflate.

9. Tire and wheel unbalanced. Static balancing alone may be satisfactory if dynamic balancing facilities are not at hand, however both are recommended. See "Wheel and Tire Balancing."

10. Steering head bearings loose. Correct adjustment and replace pitted or worn bearings and races. See "Forks."

11. Shock absorber not functioning normally. Check possible causes. See "Forks."

12. Rear fork bearings loose. Check possible causes. See "Forks."

13. Heavy front end loading. Non-standard equipment on the front end such as heavy radio receivers, extra lighting equipment or luggage, tends to cause unstable handling. Extra equipment on the front end should be held down to a minimum.

In most every case, high speed handling faults are caused by one or more of the foregoing conditions being present on the motorcycle. The possible exception will be the case where there is serious frame or fork misalignment.

Keeping tires inflated to recommended pressure is of major importance. In many cases, this attention alone applied to a solo motorcycle will remedy faulty handling at high speeds.

It is advisable to rebalance wheels and tires, at least statically, whenever casing and/or tube is replaced.
